Amethyst is the birthstone for February. It is associated with the crown chakra and has many metaphysical properties including:

• Awakens and strengthens intuition
• Helps against self-deception and poor judgement
• Clarify the thought process

Amethyst is an excellent stone for sobriety, and facing the challenges of any addiction.

Note that Amethyst will fade if exposed to ultraviolet light, so this is not a stone to put near a window.
